Custom Aluminum Expanded Metal Mesh

What Is Aluminum Expanded Metal Mesh

Aluminum expanded metal mesh is formed by CNC slitting and then stretching an aluminum sheet into a regular diamond (or hexagonal, round, or special) lattice structure in a single operation. The process produces almost no material waste, achieves high material utilization, and the stretching significantly increases the strength of the sheet.

Unlike perforated panels, expanded metal mesh is stretched directly from a single sheet, so the strands and apertures are formed in one piece — no welding, no splicing — making it stronger and more durable. Expanded metal mesh is lightweight, transportable in flat or coiled form, and easy to install, making it an ideal building material combining function and decoration.

Core Customization Capabilities

The customization of aluminum expanded metal mesh covers multiple dimensions and can be tailored entirely to project needs:

Mesh Customization: Diamond, hexagonal, round, micro, and other aperture types with adjustable aperture size and spacing.

Size Customization: Standard panel sizes and any custom dimension to fit different spans and installation methods.

Thickness Customization: Common 0.5mm–3.0mm, selected according to load and strength requirements.

Alloy Customization: Multiple aluminum grades including 3003, 6061, and 5052.

Finish Customization: Fluorocarbon, powder coating, anodizing, and wood-grain transfer.

Shape Customization: Flat, curved, folded, or cut-to-shape, combined with grids for three-dimensional effects.

Product Advantages

Compared with perforated panels, steel expanded metal, and glass louvers, aluminum expanded metal mesh offers unique advantages:

Lightweight & High Strength: Low aluminum density with high stretched-structure strength reduces building load.

100% Material Utilization: The stretching process produces no waste, offering excellent value.

Corrosion Resistance: Aluminum is naturally corrosion-resistant; with PVDF coating, service life reaches 20 years.

Open & Breathable: Open apertures provide excellent daylighting and ventilation, ideal for sunshade and ventilation systems.

Fire Resistant: Aluminum is non-combustible, meeting fire codes for public buildings.

Recyclable: 100% recyclable, supporting LEED green building certification.

Easy Installation: Coil transport and rapid on-site fixing shorten the construction period.

Common Mesh Types & Features

Applications

With its lightweight, open, and durable nature, aluminum expanded metal mesh is widely used across building scenarios:

Ceiling Systems: Open mesh ceilings create a breathable feel and light-and-shadow effects with lighting.

Facade Cladding & Sunshade: Mesh facades combine sunshade with ventilation, shaping a modern building elevation.

Fences & Railings: Mesh fences are safe and open, balancing privacy and visibility.

Louver Screens & Partitions: Indoor and outdoor louver screens divide space without a heavy feel.

Sunshade Systems: Balcony and facade sunshade panels reduce energy consumption and regulate daylighting.

Display & Brand Walls: Artistic mesh shapes build brand image.

Frequently Asked Questions

Q1: Can aluminum expanded metal mesh be customized to any mesh and size?

A: Yes. Mesh type (diamond, hexagonal, round, micro), aperture size, spacing, and panel size are all customizable. Just provide the mesh style or drawings, and we will produce to your requirements.

Q2: What is the difference between expanded metal and perforated panels?

A: Expanded metal is stretched from a single sheet, so the strands and apertures are formed in one piece with no splicing and higher strength; perforated panels remove material to form holes, with lower material utilization. Expanded metal is lighter and more open.

Q3: Is aluminum expanded metal mesh suitable for exterior use?

A: Yes. With PVDF fluorocarbon coating, weatherability reaches 20 years, widely used for facade sunshades and coastal projects. An epoxy primer is recommended for coastal environments.

Q4: Can expanded metal mesh be made into curved or folded shapes?

A: Yes. Expanded metal supports bending, folding, and cut-to-shape, and combined with grids can achieve curved ceilings, curved facades, and other three-dimensional effects.

Q5: Can samples be provided?

A: Yes. We provide free mesh samples and color swatches; clients only cover international courier costs.
